Definitions
- the present invention relates generally to a refrigeration apparatus for home refrigerator-freezer units and more particularly to a refrigeration system for the carbonator apparatus of a post-mix beverage dispenser mountable in a conventional home refrigerator.
- Both types of systems have a need for easily and efficiently cooling a carbonator used within the refrigerator dispensing system which will time-share the refrigerator's existing cooling system so that additional auxiliary refrigeration systems will not be required.
- the use of the existing refrigeration system for cooling the carbonator should, further, be effective regardless of the location of the carbonator within the refrigerator door or the interior of the refrigerator.
- any beverage dispensing system for use in a home refrigerator should be simple so that it can be easily built into or retrofitted into the refrigerator.
- an apparatus in a home refrigerator for dispensing a chilled carbonated liquid said refrigerator having a mechanical refrigeration system including a compressor an evaporator and a condenser, the improvement comprising:
- conduit means for connecting said source of cooling fluid in fluid communication with said heat exchange means
- valve means for selectively regulating the flow of said cooling fluid to said heat exchange means
- control means for operating said valve means in response to the temperature related parameters detected by said sensor means.
- the cooling fluid may be either chilled air passing over the evaporator, or a high pressure refrigerant passing through the evaporator in route to the carbonator.
- FIG. 1 is a front perspective view generally illustrative of a conventional refrigerator having an upper freezer compartment and a lower refrigeration compartment;
- FIG. 2 is a top plan view taken along lines II--II of FIG. 1 with the refrigerator door in an opened position and is illustrative of one embodiment of the present invention
- FIG. 3 is a top plan view taken along lines II--II of FIG. 1 with the refrigerator door in a closed position;
- FIG. 4 is a front cross-sectional view taken along lines IV--IV of FIG. 3;
- FIG. 5 is a front cross-sectional view of a second preferred embodiment of the present invention with a carbonator by-pass valve in a closed position;
- FIG. 6 is a partial cross-sectional view of the embodiment shown in FIG. 5 with the carbonator by-pass valve in an opened position;
- FIG. 7 is a schematic view of a third embodiment of a refrigeration system the present invention.
- FIG. 8 is a block diagram showing only the essential control components for the carbonator refrigeration system in each of the embodiments of the present invention.
- reference numeral 10 denotes a conventional home refrigerator of the type which is comprised of an upper freezer compartment 12 and a lower refrigeration compartment 14, which includes respective handles 20 and 22 for opening the doors.
- the present invention has the capability of dispensing carbonated water or a post-mix carbonated beverage including a mixture of flavor concentrate 28 and carbonated water from one of the front doors of a home refrigerator. This may be done through the lower door 14 which includes a generally rectangular access opening or recess 24 wherein a liquid receptacle (not shown) can be inserted therein and pressed against an actuation lever 26 coupled to a liquid dispenser having a discharge port (not shown).
- FIG. 2 there is shown the details of the first embodiment of the present invention wherein an entire dispensing system including the carbonator 30 located in the refrigerator door which is in an opened position.
- FIG. 3 is a view similar to that of FIG. 2, but with the refrigerator door 18 in a closed position.
- FIGS. 2 and 3 there is shown, in addition to the carbonator 30 in the refrigerator door 18, a CO 2 cylinder 48 and a control section 46 positioned adjacent each other in the refrigerator door 18.
- the syrup package 28 is centrally located in the refrigerator door 18 above a dispensing outlet in an opening or recess 24.
- Door seals 60 assist in sealing the interior of the refrigerator 14 from external atmosphere and, although shown in cross-section, run the entire vertical length of the door 18 between the door and the refrigerator.
- the carbonator 30 is surrounded by a band of heat transfer fins 62 which are enclosed within a torroidal plenum 64 (see FIG. 4).
- An insulated duct 32 within the refrigerator compartment 14 includes a carbonator by-pass valve 34 and a duct seal 58.
- FIG. 4 is a front cross-sectional view taken along lines IV--IV in FIG. 3, it can be seen that within the freezer compartment 12 there is positioned a freezer fan 36 and an evaporator 38 adjacent the rear of freezer compartment 12.
- the arrangement described enables a unique ability to cool the carbonator 30 with the use of the existing refrigeration elements, including the evaporator 38 (more clearly shown in FIG. 5), and a compressor and condenser disposed below the cabinet.
- cold air from the evaporator 38 flows past a closed carbonator by-pass valve 34 through the insulated duct 32, through a booster or carbonator fan 50, through the heat transfer fins 62 surrounding the carbonator 30, and then through a short exhaust duct 40 into the interior of the refrigerator 14.
- the carbonator by-pass valve 34 is in the closed position, the cold air from evaporator 38 is directed to the carbonator 30.
- the by-pass valve 34 is in an open position, the cold air generated by evaporator 38 is directed straight into the refrigerator compartment 14, as it would be in a conventional refrigerator.
- An ice bank detector located in controls 46 determines the position of the by-pass valve 34 such that when the ice bank detector senses a lack of an adequate ice bank surrounding the carbonator, a control system 46 will switch closed the bypass in order to direct evaporator-cooled air directly at the carbonator 30 as shown in FIG. 4.
- a conventional ice bank detector is disclosed, for example, in U.S. Pat. No.
- Water and electricity are routed to the refrigerator door 18 by flexible connectors in the hinge area (not shown).
- the carbonator 30 and its related assembly swings awaY from the insulated duct 32.
- the carbonator 30 and its related assembly reconnects to the insulated duct 32.
- FIG. 5 is a front cross-sectional view of a second preferred embodiment of the present invention, showing the carbonator by-pass valve 34 in a closed position.
- FIG. 7 is a partial cross-sectional view of FIG. 6 showing the carbonator by-pass valve 34 in an opened position.
- the second embodiment uses the refrigerator's main refrigeration system with no additional auxilliary refrigeration systems.
- the carbonator 30 is likewise surrounded by a band of heat transfer fins 62 which are enclosed within a torroidal plenum 64.
- cold air from the evaporator 38 is ducted past a closed carbonator by-pass valve 34, into the plenum inlet 63, over the carbonator's heat transfer fins 64 and then through the plenum outlet 65 into the refrigeration compartment 14. If the heat transfer fins 62 cause too much resistance to the air flow, an exhaust fan 51 for the carbonator 30 can be added to the plenum outlet 65.
- the by-pass valve 34 when the by-pass valve 34 is in the closed position, the cold air from the evaporator 38 is directed to the carbonator 30 prior to passing into the refrigerator compartment 14.
- the by-pass valve 34 When the by-pass valve 34 is in the open position, the cold a-r is directed straight into the refrigeration compartment 14, as it would be in a conventional refrigerator.
- the ice bank detector determines the position of the by-pass valve 34 such that when the ice bank detector senses a lack of an adequate ice bank surrounding the carbonator, a control system 46 will switch closed the bypass valve 34 in order to direct evaporator-cooled air directly at the carbonator 30 as shown in FIG. 5.
- Whether or not compressor under the refrigerator (not shown in FIGS. 6 and 7) is running is determined by the set point of a temperature sensor in the interior of the refrigerator.
- carbonated water from the carbonator 30 is directed to a dispensing mechanism in door 18 by way of a flexible tube routed through the hinge area (not shown).
- FIG. 7 there is shown a schematic view for a substitute refrigeration system for use as a third embodiment of the present invention.
- the system schematically shown provides an evaporator 38 which cools the interior of both the freezer 12 and the refrigerator 14.
- a three-way valve 56 will always direct a high pressure refrigerant to the evaporator 38, by-passing the carbonator 30.
- a control system 46 will oscillate the three-way valve 56 back and forth, sending high pressure refrigerant to the carbonator's cooling coils 62 for an appropriate percentage of the compressor 44 run cycle, and send high pressure refrigerant to the evaporator 38 for the remainder of the run cycle in the compressor 44.
- the mechanical refrigeration system used with the first and second embodiments of FIGS. 4 and 5 of FIG. 7 includes evaporator 38, condenser 42 and compressor 44. However, valve 56 and coil 62 would not be included in those embodiments.
- FIG. 8 there is shown a block diagram of the essential control components for the carbonator refrigeration system in each of the embodiments of the present invention.
- a temperature sensor 70 is primarily responsible for detecting the temperature within the interior of the refrigerator.
- the interior temperature of the refrigerator is to be maintained at a predetermined set point, such that when the temperature falls below the predetermined set point, the compressor 44 is activated to initiate cooling by evaporator 38 (see FIG. 7).
- Power source 72 can be any suitable power means available for running a standard refrigerator.
- the ice bank detector 74 detects the lack of an adequate ice bank (below a predetermined thickness) surrounding the carbonator 30 such that detection of an adequate ice bank will operate to open switch 34 and allow chilled air to pass directed into the refrigerator compartment 14. Conversely, if an inadequate ice bank is detected, the switch 34 will close allowing chilled air to cool the carbonator 30.
- the three-way valve 56 operates as described in connection with FIG. 7 whereby when the ice bank detector senses the presence of an adequate ice bank on carbonator 30, the three-way valve 56 will always direct the high pressure refrigerant to the evaporator 38, by-passing the carbonator 30.
- the ice bank detector 74 senses a lack of an adequate ice bank on the carbonator 30, the three-way valve 56 will oscillate to direct high pressure refrigerant to the carbonator cooling coils 62 for an appropriate percentage of the compressor 44 run cycle, and send high pressure refrigerant to the evaporator 38 for the remainder of the compressor 44 run cycle.
